Introduction, definition of the data objects and relationships together with the operations on the structures supported in the data language. A data language consists of a data definition language (DDL) that defines the data objects and relationships, and a data manipulation language (DML) that expresses operations on the objects defined in the DDL.作者: agenda 時(shí)間: 2025-3-22 08:02 作者: Aprope 時(shí)間: 2025-3-22 12:19

Yao’s cost model uses accesses to external storage as its cost metric. We have extended Yao’s cost model to include the algorithms necessary for processing queries against GDM.作者: 梯田 時(shí)間: 2025-3-22 22:09 作者: AWRY 時(shí)間: 2025-3-23 03:21
